Actually I made this game ENTIRELY because I hadn't yet made a boss for Ruptured. The only things it has in common really are the basic physics and the graphics. This was my learning experience to figure out how to make a boss, now I just gotta have it pick its own moves and implement it. You can wishlist Ruptured on Steam here: https://store.steampowered.com/app/1987800/Ruptured/
There is also a discord server where you can follow the development of Ruptured: https://discord.gg/YvW2qBfj5C
Thanks for playing!
